If you're out there working in it, frequent breaks and lots of water are needed. C.J., Richard and the team from Booker Mechanical recently changed out an “A.C.” unit for us as everyone’s air conditioning units are “humming along.” Yesterday designated the 110th anniversary of the invention of modern air conditioning. In the 1900s, a Brooklyn printing plant was the first building in the world to be air conditioned by Dr. Willis Haviland Carrier. Older Baton Rouge homes utilized an attic fan to move air from room to room. Carrier’s cooling plant divided air into two streams, one heated, the other cooled. In each room, these two air streams are proportionately mixed to produce a desired temperature. And...on this date in 1689, lightning zapped the altar in the church of Saint-Sauveur, in Ligny, France. According to the “Almanac of the Infamous, Incredible and Ignored,” fifty witnesses watched a statue of Christ levitate. Altar cloths were scorched and curtains were blown off their rings but the rings remained on the rod. In 1812, in Combe Hay, Somerset, U.K. six sheep were killed by lightning but tattooed pictures of the landscape were on their skin. Two similar incidents occurred in Greece where a sailor, struck by lightning, had a "shadow graph" of the number 44 on his body and was attached to adjacent rigging. Another sailor in the Adriatic was hit while sitting below the mast. Imprinted on his groin was the image of a horseshoe, nailed to the foremast.
